Currently operating a Plesk server with 10-15 Domains. We are currently increasing the number of MISSION CRITICAL applications for our customers hosted on the server and as such we need to ensure this data is protected and if the server should go down that another server takes its place ensuring minimal downtime and data loss.
Most of the sites run MySQL databases on Plesk 9.
All of the sites have email which is heavily used and the server is used for Storage for most accounts (IMAP).
- Setup a second server to act as a standby server in case primary server goes down. (Second server yet to be ordered - will take advise)
- SQL should match at all times with primary server.
- Emails should be sync'd 3 times daily. (will take advise on this).
- Server backups from Primary server to be stored on secondary server AND a 3rd party FTP storage (will take advise on this)
Will take advise on any other considerations. This is the first time I have approached this topic so it is new to me.
